SAB introduced the Direct Drive on this class of helicopter and as you may know, we sold more than 2500 KITS.
However, in pursuit of improving performance, we determined that the Direct Drive could no longer be the correct solution. The evolution of the RAW 420 will use a motor belt drive.
This is how the RAW 420 Competition was born. Lighter, faster, more flexible in the selection of the desired head speed at a higher performance level.
